Average time to render frame

[bugreport987]

I play games through a capture card and although the frame rate is smooth and there is no perceptible lag I often miss my moment to react in games like sonic generations so I have to press the button before I swing on something and in ratchet and clank rift apart I'll get hit and I won't know why. The source is smooth on what I'm seeing but what I see and what's happening in the game are ever slightly different. at a 2.5 ms render time per frame. At 30 fps is that a 75 ms render time

Capture cards/software are for capturing, not extremely low rendering time. This is why some of them have pass through.
Ideally you want resolution and frame rate to match from source to display (including preview size) to avoid conversion time. Make sure nothing else is using your GPU.
Another option would be to play the games directly on your monitor using a splitter from the source.

Thank you that is very helpful I have an hdmi splitter I used to use for getting audio from old vhs tapes by splitting the audio to a small TV and using it as a speaker. I did make my own hdr solution which filters what is displayed on the pc it looks really good. However I've had to make the canvas resolution match the source resolution so I suppose it's pointless. When recording it upscale the source from 1080p to 4k and it looks really good. But when playing at 4k through obs with the source at 1080p it looks quite bad. I have an old version of windows 10 that my old computer requires to play fast through the capture card. If the capture card was 4k it would be worthwhile it's not so I suppose I could try it. I've had fun playing ratchet and clank rift apart through the capture card but what I see through the capture card and what's actually happening are not the same I believe the game is fluid but I realize I'm reacting to things that happened after I realized they happened so ill get hit by bullets I don't see still a lot of fun and looks quite good. The youtube videos I make are extremely high quality and are better than the hardware I have they look quite good and have a low bit rate so they're easy to upload intel has pretty good codecs
But I wasn't necessarily looking for advice on playing through the capture card but for streaming its really important to have no latency at the source. Technically services like geforce now have nanoseconds of latency with the source they provide you. The rest of the latency comes from your internet. I noticed this when I swing with moonligh5 i can hit the swings in sonic generations within milliseconds but on my capture card I have to press the button before I see the swing. Inferring from that the total latency is the average latency multiplied by the number of frames. Because if the total latency was 2.5 ms then it'd be much better than geforce now. When I livestream my total latency not average latency through obs is 2ms with a camera attached to my laptop. Throughout much of the u.s the total stream latency is 67 ms which is pretty good. 65ms plus 2ms It's not possible to stream to Europe or Japan unless they do something special to their connection to artificially lower their ping in which case it may be possible to stream to them.

Honestly I think there should be an update that says total latency equals average latency times total number of frames no variables as to not increase the latency I think its just a helpful statistic to know for setting up a livestream
